Should fast food be illegal?

According to the logic of those who want to keep marijuana illegal, should we not also illegalize fast food, as that contributes to arteriosclerosis? Or junk food and candy as well, as that can lead to diabetes? And maybe video games as well since they make people lazy? Also alcohol as that can lead to liver failure and tobacco because it causes lung cancer? Should we just illegalize everything that is indulgent and/or unhealthy and just all lives as dictated by our nanny Government?
